The tradition of Watch Night services in the United States dates back to December 31, 1862, when many Black Americans gathered in churches and other venues, waiting for President Abraham Lincoln to sign the Emancipation Proclamation and thus free those still enslaved in the Confederacy. It's still being observed each New Year's Eve, at many multiracial and predominantly Black churches across the country. As the Civil War raged on, Lincoln issued a preliminary decree on September 22, 1862, declaring that enslaved people in the rebellious Confederate states were legally free. However, this decree — the Emancipation Proclamation — would not take effect until the stroke of midnight heralding the new year. Those gathering on the first Watch Night included many African Americans who were still legally enslaved as they assembled, sometimes in secrecy. Over its 160-year history, Watch Night has evolved into an annual New Year's Eve tradition — it not only commemorates freedom from slavery, but also celebrates the importance of faith, community and perseverance. The museum notes that the Watch Night worship services were traditionally followed by a "fortuitous meal" on New Year's Day, often featuring a dish called Hoppin' John.
